Friend is a full time pet sitter and I have 2 male cats, I sometimes book her to look after them when I'm away.
Both males are older and very affectionate, they like just sitting with you all day but still a little playful sometimes.
Got them together a year ago and neither have ever scratched or bitten or anything like that. One will occasionally bat you playfully, anyway friend has sat for them several times.
She was talking about another cat she sits for who's bitten and scratched her. She then dropped into the conversation 'Oh your cat scratched me 3 times but I just accept it for what it is."
I was surprised because she'd never mentioned it, i asked her what had happened, she said she'd tried to stroke him and he did that. I felt bad because as I say he's never done it to me or my partner before, I felt embarrassed really.
Not sure what I could do? I mean there's no way of knowing with these things or if I could prevent it but I do feel bad.
